"As someone that knows [Joe] very well, I can tell you that he found his partner and the love of his life," Nick said. "That's all that matters. It's a beautiful thing." And when asked whether the family would be putting Sophie through some tests while they're all together over the upcoming holidays, Nick said that it's "all love" with her. "She was with us last year a bit, as well, so she sort of already had her first Jonas Christmas experience," he added, explaining that the "Jonas Christmas experience" mostly entails a ton of food. "Mom's got the cookies out, everything's happening," he said. "Good movies, good times spent around the fire — that's the vibe."

Nick has shown plenty of love and support for Joe and Sophie since they announced their plans to tie the knot last month. Shortly after the pair confirmed their happy news on Instagram with a photo of the Game of Thrones star's hand — sporting her sparkly engagement ring — resting on top of Joe's hand, Nick reposted the photo and added an excited caption. "Ahh! Congratulations to my brother... and sister in law to be on your engagement. I love you both so much," he wrote.

And earlier this month, after Joe and Sophie celebrated their engagement with a gathering of their friends and family, the DNCE singer's younger brother shared a series of photos taken in the party's photobooth, including a group photo of all four Jonas brothers (don't forget about Frankie, AKA the Bonus Jonas!), Sophie, and Kevin Jonas's wife, Danielle, and another shot of just Kevin, Joe, and Nick laughing together. "Beautiful night celebrating beautiful people. #JOPHIE" Nick captioned the Instagram post.
